Fighting with cmake

[ikawrakow]

cmake has the unpleasant habit of using "response" files to put stuff such as list of include directories. But that confuses vim (or at least it does the way I have set it up) when I edit CUDA files. I had tricked cmake into not using "response" files, but instead adding all nvcc command line options into compile_commands.json. But at some point that stopped working, I guess after a system update. I hate it, so this PR restores the desired behavior. I had to add

            set(CMAKE_CUDA_USE_RESPONSE_FILE_FOR_INCLUDES 0)
            set(CMAKE_CUDA_USE_RESPONSE_FILE_FOR_LIBRARIES 0)
            set(CMAKE_CUDA_USE_RESPONSE_FILE_FOR_OBJECTS 0)

another time at the end of the block related to CUDA in CMakeLists.txt, else something was making my request at the beginning of the CUDA block to be ignored.
